The old version of this is a fast and frantic triple strike arena, with no health and a whomper; it seems that Alfie, back when he was a NAB player, made this version, which Boom has now released. Here you get a couple of corridors leading off from one side - and this is what they lead to. A nice quiet side room, with health, a hypershot, and a swimming pool to chill out in. Oh, and you can find a megapower at the bottom of the pool! The only other change I noticed is a health-belt in the centre of the main area, by the whomper...
So, does this make for a better map than Morbias ][ Remix? Well, depends on how you like to play the arena. I suppose it would be handy, when low on health, to be able to dash away from the fighting and recharge your batteries, but would the other players let you do that?
Is this an improvement, or is it really a diluted version? Difficult to say. The add-on area has been nicely done, certainly, and it is nice to get the choice between the two versions...
